 * [`functions`](https://docs.rs/rusqlite/~0/rusqlite/functions/index.html)
   allows you to load Rust closures into SQLite connections for use in queries.
   Note: This feature requires SQLite 3.7.3 or later.
+* `window` for [window function](https://www.sqlite.org/windowfunctions.html) support (`fun(...) OVER ...`). (Implies `functions`.)
 * [`trace`](https://docs.rs/rusqlite/~0/rusqlite/trace/index.html)
   allows hooks into SQLite's tracing and profiling APIs. Note: This feature
   requires SQLite 3.6.23 or later.

 * `hooks` for [Commit, Rollback](http://sqlite.org/c3ref/commit_hook.html) and [Data Change](http://sqlite.org/c3ref/update_hook.html) notification callbacks.
 * `unlock_notify` for [Unlock](https://sqlite.org/unlock_notify.html) notification.
 * `vtab` for [virtual table](https://sqlite.org/vtab.html) support (allows you to write virtual table implementations in Rust). Currently, only read-only virtual tables are supported.
+* `series` exposes [`generate_series(...)`](https://www.sqlite.org/series.html) Table-Valued Function. (Implies `vtab`.)
 * [`csvtab`](https://sqlite.org/csv.html), CSV virtual table written in Rust.
 * [`array`](https://sqlite.org/carray.html), The `rarray()` Table-Valued Function.
 * `i128_blob` allows storing values of type `i128` type in SQLite databases. Internally, the data is stored as a 16 byte big-endian blob, with the most significant bit flipped, which allows ordering and comparison between different blobs storing i128s to work as expected.
 * `uuid` allows storing and retrieving `Uuid` values from the [`uuid`](https://docs.rs/uuid/) crate using blobs.
 * [`session`](https://sqlite.org/sessionintro.html), Session module extension. Requires `buildtime_bindgen` feature.
+* `extra_check` fail when a query passed to execute is readonly or has a column count > 0.
+* `column_decltype` provides `columns()` method for Statements and Rows; omit if linking to a version of SQLite/SQLCipher compiled with `-DSQLITE_OMIT_DECLTYPE`.
+* `collation` exposes [`sqlite3_create_collation_v2`](https://sqlite.org/c3ref/create_collation.html).
